Sensors, Vol. 23, Pages 2592: Modeling of Rapid Pam Systems Based on Electrothermal Micromirror for High-Resolution Facial Angiography
huqing Wang In this paper, a portable photoacoustic microscopy (PAM) system is proposed based on a large stroke electrothermal micromirror to achieve high resolution and fast imaging. The crucial micromirror in the system realizes a precise and efficient 2-axis control. Two different designs of electrothermal actuators with “O” and “Z” shape are evenly located around the four directions of mirror plate. With a symmetrical structure, the actuator realized single direction drive only. The finite element modelling of both two proposed micromirror has realized a large...

Sensors, Vol. 23, Pages 1900: Multi Modal Feature Extraction for Classification of Vascular Dementia in Post-Stroke Patients Based on EEG Signal
This study used 19 EEG channels recorded from normal elderly, post-stroke with mild cognitive impairment, and post-stroke with dementia. The QEEG method used for feature extraction includes relative power, coherence, and signal complexity; the evaluation performance of normal-mild cognitive impairment-dementia classification was conducted using Support Vector Machine and K-Nearest Neighbor. The results of the classification simulation showed the highest accuracy of 96% by Gaussian SVM with a sensitivity and specificity of 95.6% and 97.9%, respectively. This study is expected to be an additional criterion in the diagnosis o...

Sensors, Vol. 22, Pages 4310: Cardiovascular Disease Diagnosis from DXA Scan and Retinal Images Using Deep Learning
In this study, we aimed at diagnosing CVD using a novel approach integrating information from retinal images and DXA data. We considered an adult Qatari cohort of 500 participants from Qatar Biobank (QBB) with an equal number of participants from the CVD and the control groups. We designed a case-control study with a novel multi-modal (combining data from multiple modalities—DXA and retinal images)—to propose a deep learning (DL)-based technique to distinguish the CVD group from the control group. Uni-modal models based on retinal images and DXA data achieved 75.6% and 77.4% accuracy, respective...

Sensors, Vol. 21, Pages 8099: Detection of Collaterals from Cone-Beam CT Images in Stroke
Sobri Muda Collateral vessels play an important role in the restoration of blood flow to the ischemic tissues of stroke patients, and the quality of collateral flow has major impact on reducing treatment delay and increasing the success rate of reperfusion. Due to high spatial resolution and rapid scan time, advance imaging using the cone-beam computed tomography (CBCT) is gaining more attention over the conventional angiography in acute stroke diagnosis. Detecting collateral vessels from CBCT images is a challenging task due to the presence of noises and artifacts, small-size and non-uniform structure of vessels. T...

Sensors, Vol. 21, Pages 7014: Combined Use of EMG and EEG Techniques for Neuromotor Assessment in Rehabilitative Applications: A Systematic Review
astropietro Electroencephalography (EEG) and electromyography (EMG) are widespread and well-known quantitative techniques used for gathering biological signals at cortical and muscular levels, respectively. Indeed, they provide relevant insights for increasing knowledge in different domains, such as physical and cognitive, and research fields, including neuromotor rehabilitation. So far, EEG and EMG techniques have been independently exploited to guide or assess the outcome of the rehabilitation, preferring one technique over the other according to the aim of the investigation. More recently, the combination of EEG and...

Sensors, Vol. 19, Pages 1224: Low-Cost Tracking Systems Allow Fine Biomechanical Evaluation of Upper-Limb Daily-Life Gestures in Healthy People and Post-Stroke Patients
satti Since the release of the first Kinect in 2011, low-cost technologies for upper-limb evaluation has been employed frequently for rehabilitation purposes. However, a limited number of studies have assessed the potential of the Kinect V2 for motor evaluations. In this paper, a simple biomechanical protocol has been developed, in order to assess the performances of healthy people and patients, during daily-life reaching movements, with focus on some of the patients’ common compensatory strategies. The assessment considers shoulder range of motion, elbow range of motion, trunk compensatory strategies, an...

NLP Logix, Mayo Clinic partner for AI analysis
Jacksonville-based NLP Logix rolled out its first medical use for artificial intelligence in partnership with Mayo Clinic, deploying the technology on brain MRI scans. The company announced in July that it was partnering with Mayo to develop AI that could confirm stroke diagnoses. The current technology, unveiled Tuesday at the Mayo Clinic Convergence Neuroscience 2017 Conference in Atlanta, can identify white matter hyperintensities (WMI), which is a critical factor to monitor in patients with…

Cranial reconstruction using allogeneic mesenchymal stromal cells: a phase 1 first ‐in‐human trial
This study assessed the effectiveness of treating cranial defects with a combination of allogeneic mesenchymal stromal cells (MSC) on a ceramic carrier and polymer scaffold, to produce viable bone and healing of a cranial void. Patients underwent a baseline CT scan for construct design. Two sets of interlocking moulds were 3D‐printed to enable shaping of two polymer meshes which formed the boundaries of the construct corresponding to restoration of the skull interna and externa. In vitro expanded donor MSC were seeded onto ceramic granules in a GMP facility. The inner mesh was placed in theatre, followed by the cell‐lo...

GMC invests $1.7M in 128-slice CT scanner
Gwinnett Medical Center has invested $1.7 million in a computed tomography (CT) scanner at its Lawrenceville hospital. The 128-slice CT scanner will be used in GMC Lawrenceville's emergency room, which is a Level II trauma center. The CT scanner boasts lower radiation levels than conventional x-ray devices, and allows physicians to see what was previously unseen, a hospital spokeswoman noted. The device will be used for bariatric, cancer, stroke and cardiac patients because it offers 4-D imaging,…
